Abstract:
A feedstock for injection molding includes a ceramic filler that is sinterable to produce a ceramic with a positive temperature coefficient of electrical resistance, a matrix for binding the ceramic filler, the matrix having a melting point lower than a melting point of the ceramic filler, and metallic impurities. A content of the metallic impurities in the feedstock is lower than 10 ppm.
